THREE-IN-ONE VALVE.

Application med Tehran-11 2, 1923. Serial m. 618,578.-

To all whom it ma concern: a v g Be it known that I. Gnome Commons. a citizen of Grreece, residing at Monrovia-'. in the county of- Los Angeles and State of California, have ihvented new and useful 'Improvements .iwThree-In-One Valves. of

which thefollowingis a specification.

This invention relates to valves and more particularly to a' three-in-one or mixing.

valve.

It is an object -of the present lnvention to provide a simple, practicable, substantial and easily operative valve including means whereby either hot or cold-water or the valve members. and a further obiect is having to provide-a lock for fastenin in open position the self-closing valve parts.

Other objects and advantages will be made manifest in the following specification of an embodiment of the invention illustrated in the accompanyingdrawings,- wherein 4 Y Figure 1 is a side elevation of the im' proved valve.

Fig. 2 is a topplan of the same.

Fig. 3 is a front elevation.

Fig. 4 is a central longitudinal section through the .valve. I Fig. 5 is a section on line 5-5 of Fig. 4 showing the valve latching device.

Fig. 6 is a section on line M of Fig. 4.

Fig. 8 is a sectional. detail on the lines 8-8 of Figs. 4 and 7.-

The valve of the present invention consists of a suitably shaped shell or body 2 a forwardly promoting discharge spout 3, the duct 3" of'whlch communicates with the lower interior portion of the shell, and in which portion'is arranged a. rotative core 4 which may be inserted upwardly 'throu h the bottom of the shell and 'retaine as by a bottom closure 5 which may be screwed into place. The shell 2' is provided with an upper ichamber in which is mounted a spring 6 "normally-bearing down on awasher 7 havthe shell body, these side walls terminating in shoulders 10 adjacent the upper end of the core 4.

This core is provided with a plurality of apertures 12 and 13. Fig. 7. which are adapted to be selectively moved into reg? ister with the adjacent ends of the inlet ports through the'nipples 14, so that hot on I cold water, or a mixture, may be dischargerh from the valve. Hot and cold water are admitted asbymeans of a hot water pipe H and a cold water pipe C which are connected to nipples 14 provided on the sides of the shell 2 and which have passages in a higher plane than the "pocket 4 in the .valve core 4 which is rotativelv mounted. so.

that. these ports can be shifted so. that only hot water will be discharged through the spout or only cold water will be dis-' charged, or a mixture of the same, as will be the case when the. valve core 4 is posi- 'tioned as shown in Fig. 7.

Suitable operating means are provided for rotating the valve core 4, and such means is shown as includin a radiallv extending handle 15 which is pivotallv connected at 16 to the upwardlv extending stem'17 of'a plug 18- which issadapted to move telescopically in a; pocket 4 in the top of the'core 4. The pocket 4 communicateswith the spout 3. The plug 18 opens and closes the ports 12 and 13. The handle is adapted to be rotated and therebv to rotate the stem 17 and the plus 18 which is of noncircular cross section. or otherwise is nonrotatively attached to the core 4 so that the latter can be turned to the desiredv The handle 15 having been positioned so as .to register the ports 12 and'13 to-accom- 'plish the discharge of hot and cold water,

or a mixture, it is then pressed downwardly $0538 to rock on the u per end'of the'shell 2 as the pocket a fulcrum and thus ift the Hand the plug. 18 a suflicient degree to open communication between the ports 12 and 18 and the pocket 4".- If the plug ports have.

- tative plug 18 and, therefore, the flow of water will be cut off as soon as pressure is relieved from the handle 15 by the downward movement of'the plug 18 into a pocket 4*. It is desirable to provide meansforfastening thevalve elements, if desired, in open position so as to permit the flow of water fora desired length of time without requiring the holding down of the lever 15. To

that end a sliding bolt or latch 22 is mounted in the handle 15 which is provided with a lateral pocket 3 in which is exposed a button 24, on the adjacent end of the latch 22. The opposite end of the latch is shown as slotted at 25 to pass around the stem'17 and passes outwardly so as to be shifted .mto upper and lower grooves 26 provided in an upwardly projecting wall 27 on the shell 2. When the latch 22 is fully withdrawn and the handle is in full closing position, the latch clears or rests below the lower slot 26 and flow is entirely out ofi. Assumin a small flow is desired, the handle is ti ted v slightly to bring the latch into re ister with the lower slot 26 and the latch is t en shifted in the handle to engage in this slot. If a larger flow is desired, the handle is tilted further and the latch is engaged in the upper slot '26. A still larger flow. is obtained by tilting the handle down to such an angle as to bring the latch over the top of the wall 27 when the latch is again shifted to bear on the top end of the wall, thus holding the valve in full open position.

i The latch. 22 is shown as gaged by a spring finger30 operating to hold the latch in its difierent positions.

To prevent drain throughthe-topoper-I ating joints in the shell, the spout 3 is pro vided with a drain passage 3 inclined up- I wardly. and communicating with the spring chamber of the shell so that water passing upwardly into this chamber will be free to pass or drain out through the spout .3. s

It will be seen that the turning of the handle 15 will belimited in its lateral ex tremes by enga ement with the contiguous ends of the wal or flange 26 when the valve is fully open to serve either hot or cold water; v v

Further embodiments, modifications and variations may be resorted to within the spirit of the invention as here claimed. s
